I found it quite easy to adapt and use. support isn't too bad for it, a ticket may take around 24 hours to be answered but for a Freebie thats is good.
The scripts themselves are fairly easy to change and adapt for anyone with a bit of html/php knowledge. I stuck to the standard theme and just changed colours and graphics. I tried to bridge SMF forum but the script fails and haven't had an answer from the mod author.
The built in forum is very basic thats why I added SMF . the chatroom is good, the blogs could do with a couple of features added.
There is a host of Mods, both free and Pay for. I have just got one called Hotshots enabling video, mp3 to be played on the
website hosting. will install it later.
The only problem I had was over the activation e-mail not displaying the link as clickable and sometime people didn't recieve it, so I changed the output template and I activate users accounts. seems to work OK . I tried another supposed free social dating script called Dolphin, there were more bugs in that than an ant's nest, mods and skins cost an arm and a leg, . One of the most difficult and frustrating things I have tried.
All in all I rate Phpzabi quite highly and would hesitate to give it a run
If anyone wants to have a proper look here is the address.
